This invention relates to means for suspending a garbage disposal device from the drainage outlet of a kitchen sink or the like, having a relatively large outlet.

One object of the invention is to provide a drainage sleeve or Outlet liner which 'is easyto form, is highly durable-and eflicient, iseasy to mount in the outlet of a sink and is easily shaped at its lower endk for attachment Vdirected bead is formed by the formation of the indi- `cated groove so that such bead may serve as a seat for an appropriate stopper.

An additional object of the invention is to provide a novel, preferably yieldable, stopper or closure structure to co-Operate with. the mentioned seat.

It is 'additionally an object of the invention to provide ring means, including split'ring means and continuously r annular ringf means which may be readily mounted upon the lower end of said sleeve, through the medium of said outwardly directed groove for attachment to the upper end of agarbage grinder or similar disposal device to be suspended from the sink through the medium of the drainage sleeve.

Other objects of the invention and various features i of construction thereof will become apparent upon referA ence tothe following speciiicationand accompanying drawings wherein certain embodiments are illustrated.

inthe drawings, Fig. l illustrates the principal features of this improvement in the form of a thin stainless steel outlet liner or drainage sleeve 10 spun or otherwise shaped as required, a yieldable rubber stopper 12 having a metal cap member 13 at the top thereof, abind ring 14 clamping the sleeve lil to the sink S which supports the struc ture, a special snap ring 15 which serves asa supporting ring, a carrying ring or clamp ring 16 which is clamped beneath a co-operating mounting ring 18, through the medium of screw bolts 20y which clamp and bind the rings 14, 15, 16 and 18 in operative position, a disposal device 22 which is suspended from the sleeve 10 through the medium of a resilient, freely-suspending rubber ringlike connecting neck 24, which is tensioned by the weight of the device 22, a flange-like suspension or supporting ring 25 mounted in the rubber ring neck 24 and clamped between the carrying rin-g 16 and 4the mounting ring 18, and a flexible splash guard 26, also of rubber, preferably removably mounted in the inner wall of the rubber suspending connectingneck 24 and providing a small 'central water passage 28.

The sink sleevel or outlet linerl 10 carries at its top a sloping annular ange bearing upon a corresponding seat of the bottom of the sink S. The lower end of the sleeve lil is spun or rolled inward to form an annular bead 32 which provides at its upper side an annular seat f 33 (Fig. 1A), the lower extremity of the sleeve being substantially in line with the outer sleeve wall as indicated atv 34 whereby to engage with the inner edge of the rubber suspending ring 24 to complete a sealing contact as indicated in Fig. l. Above the bead 32 a plurality of inwardly struck positioning detents 35 is provided (see also Figs. 2 and 7), which are illustrated as being ve in number and serve to center the stopper 12 and its cap 13 to provide an annular water passage 36 (Fig. 2) between the main wall of the sleeve 10 and the annular edge ofthe stopper 12 and its cap 13. The rubber stopper 12 is provided with an annular series of integral rubber projections or retaining fingers 37 which may be, for example, four in number as indicated in Figs. l

and 3, or live in number as indicated in Fig. 8, or as desired. These fingers 37 may normally be rested upon the seat 33 of the bead 32 so as to hold the stopper in elevated position for the flow of water through the annular passage 36. When desired to retain water in the sink S, the stopper may be forced downward through the medium of the cap 13 to deform the positioning fingers 37 so that they snap below the bead 32, whereupon an annular integral rubber sealing iin 38 cornes into sealing engagement with the seat 33. Where the metallic cap 13 is employed to provide a knob for manipulating the stopper, its annular rim folds around an uppermost annular rib 39 which is snapped into the corresponding rolled cap portion; On the other hand, as illustrated in Fig. ll, an integral knob 39a` may be provided and the annular rib 39 omitted. In either case, when it is desired to lift the stopper, either to permit iiow of water through the tion of this vring 15 provides anupwardly facing annular snap ring 15.

3 seat upon which rest inner annular portions of the mounting ring 18. For the purpose of strengthening the ring 18, it is provided with a peripheral down-turned annular ange 42 which also encloses the carrying and clamping ring 16 when the parts are `assembled as illustrated in Fig. 1. If desired, intermediate portions of the ring 18 between the bolts 20 may be downwardly offset to provide stiiening grooves 43. For the most part, the inner edge of the ring 18 provides seating portions 44 (Figs. l and 3) whose inner edges are flush with the outer main wall of the sleeve 10, such seating portions 44 overhanging the mentioned upper annular seat `of the split However, portions of the ring 18 intermediate the seating portions 44 (illustrated as three in number in Fig. 3) are struck up to form upstanding lugs 45 which, at their upper ends, provide inner faces which bear against the outer Wall of the sink sleeve to prevent edges of the seating portions 44 from slipping into the groove 40 above the ring 15 and thus causing partial disengagement of the seating portions 44 from the snap ring 15. The lower portions of the lugs 45 may be such as to bear upon the corresponding edge portions of the ring 15, as seen at the right of Fig. 1. As seen especially in Fig. 3, the lugs 45 are of sufficient circumferential length to span the narrower struck-up detents 35, so that the lugs 45 Will not fall into the external depressions opposite such detents 35. In order to insure against tearing of the metal which the lugs 45 are bent up, shallow notches, such as indicated at 46 in Fig. 3, are formed at t he opposite ends of each lug. Opposite each lug 45 there is provided a bolt hole to receive a threaded portion of the respective bolt 20. In order to provide a sucient number of thread convolutions, when each hole is punched the metal is directed downward in the form of a boss 48 (Figs. l and 4) therearound, the inner wall of this boss being threaded throughout its length and thus providing a good seat for the bolt. The clamp ring 16, which underlies the mounting ring 18, is retained in the illustrated clamping position by nuts 50 threaded onto the lower ends of the bolts 20, the bolt ends being received preferably in one slot 52, as seen at the right of Figs. 1 and 6, and in two Unthreaded holesj53 as also seen in Fig. 6. Thus, when the bolts are positioned in the ring 18 and the clamp ring 16 is drawn up by the nuts 50, the parts are retained in clamping relationship.

The carrying ring 16 is preferably cup-shaped in crosssection, such shape being provided by an inner annular upstanding ange 54 (Figs. l and 6) and an outer annular upstanding ange 55. As seen especially in Fig. 1, the inner flange 54 is shorter than the outer flange 55 so that the exposed portion of the flange-like suspension ring vulcanized in the rubber neck 24 is clamped between such flange S4 and the adjacent ring portion 18 at the time that the upper edge of the outer annular flange 55 is clamped against the under side of the corresponding portion of the mounting ring 18. By these means the rubber suspending neck 24, which supports the disposal device 22 is securely suspended in anchored position by the rings 16 and 18 and the bolts 20. In order to tension and seal the upper end of the'sink sleeve 10 in the drain opening in the bottom of the sink S, the metallic bind ring 14 is forced up against a rubber or similar sealing ring 58 by means of the upper ends of the bolts 20 which are integrally headed at 60 for rotation of the bolts independently of the nuts 50. For centering purposes the upper end of each bolt 60 is reduced to a small stud 61 to enter a corresponding small opening 62 in the overlying portion of the ring 14. To accommodate different sink dimensions and other dimensions, portions of the ring 14 may be offset downward, as seen at the right of Fig. l and as indicated at Fig. 2, intermediate portions as seen at the left of Fig. l and also in Fig. 2 being in the general plane of the ring. Thus, the ring 14 may be rotated as required with respect to the bolts 20, as a consequence o f which, where three bolts 20 are employed,

six holes 62 will be provided. Additionally, alternating portions of the ring 14 in the dat areas opposite the respective holes 62 are notched out at 64 to accommodate, if desired, the upstanding lugs 45 during initial installation procedure, the ring 14 being eventually elevated toward the sealing ring 58 and rotated about 60 to the position illustrated, whereupon the bolts 20 are set as previouslv described to compress the sealing ring 58.

The snap ring 15, which is particularly illustrated in Fig. 5, is especially shaped to provide for snapping it over the lower extremity 34 of the sleeve 10 so that it will enter and snap into the external groove 40. Larger portions of the ring 15, as indicated at 65, conform in curvature with the inner wall of the groove 40 to engage therewith when in operative position, the ring being split to provide a small gap 66 to permit springing of the ring into place. The portion of the ring opposite from the gap 66 is somewhat cut out at 67 on an arc centered at 67a to facilitate catching of the ring at one end adjacent the gap 66 and at the cut-out 67 so that the opposite end of the ring on the high side may be spread with a tool over the respective portion of the lower end 34 of the sleeve 10. To facilitate such passage of the mentioned opposite end of the ring 15, short portions 68 at gap 66 are considerably narrowed on the inner side of the ring at each end and adjacent portions 69 are tapered olf therefrom on an arc centered at 69a which slightly spaced from the ring center indicated at 70.

By means of this structure, the ring 15 is readily installed in the groove 40 after locating the sleeve 10 and rings 14 and 18 by positioning one-half the ring 15 in one side of the groove 40 with the cut-out or notch 67 caught over the extremity 34 of the sleeve, the free end of the ring 15 being then sprung over the remaining portion of the sleeve 10 by any convenient tool such as a screw driver. Since the parts 65 engage the bottom of the groove 40 thereby preventing compression of the ring 15 the peripheral portions of the ring 15, being in the form of a true circle, provide a continuous seat for the inner edge portions 44 of the mounting ring 18 as the latter is accurately positioned by the upstanding positioning lugs 45. The rubber suspending ring 24 is therefore properly retained through the medium of its metallic support ring 25 which is clamped between the mounting ring 18 and the clamp ring 16 through the agency of the nuts 50 on the bolts 20.

As illustrated, the lower end of the rubber suspending neck 24 is secured to the upper end of a section 75 of a garbage grinder housing either by being vulcanized thereto at 76 or by being clamped thereon by an outer spring member 77, or both.

The previously mentioned splash guard 26, which is of exible rubber, is desirably formed with a rim portion 80 which may be reinforced with a spring ring 81 and is snapped into a groove 82 lying above a supporting shoulder 83 of the suspending ring 24, The flexible diaphragm portion of the splash guard 26 is in the form of a plurality of yieldable segments 84 formed by slits 85 which may terminate in round punched holes 86 which prevent tearing. The previously mentioned opening 28 which provides for normal flow of Water preferably has an area approximating about one tenth to one eighth of the cross-sectional area of the internal diameter of the rubber ring 24, so that noises from the underlying grinding apparatus, when operating, might be blocked by a normal iow of water past the elevated stopper 12, or through the steel sleeve 10 if the stopper is complet-ely removed. For the insertion of large pieces of waste to be ground, the segments 84 yield readily to permit their passage.

One form of stopper is shown in Fig. 1 where only ing supportinglugsA 90 which correspond in number with/the inwardly struck detents 35 ofthe sleeve 10 and are adapted to rest upon the tops of such detents to permit thepassage of-water between the main wall of the sleeve andthe-periphery of the stopper 12, the stopper being rotatable-to alignthe lugs 90 with the spaces between the detent-s 35 so thatthe stopper may be lowered to `rest upon the upwardly facing seat 33 of the bead 32. In'this case the underlying annular sealing lip 38 may be retained or, as seen in--Fig. 10, the main annular wall of the stopper will be positioned and sloped off as indicated at 92 so as to' enter the space within the bead-'32 andengagevthe Yinwardly-facing wall of the bead 32 in sealing relationship. As illustrated in Fig. ll and as previously described, a stopper structure with an integral knob 39a like that of Fig. l0 may be used where the projections 37 are employed and the annular sealing lip 3S is retained at any appropriate position above the deformable projections 37.

With respect to materials of which various members of the present construction are produced, the various Stoppers are made of such rubber that the body portions 12 possess suicient rigidity to maintain substantially the shape shown, this including the integral knob 39a when used, while at the same time the narrow or fingerlike projections 37 will support the Stoppers of Figs. 1 and ll in drainage position while being at the same time deformabl-e to be pressed past the inner annular bead 32 for seating of the fin or lip 3S on such bead 32, such annular lip or iin being capable of supporting the stopper under any head of water ordinarily encountered in a sink. The rubber of these Stoppers is also of such character that the broad lugs 90 of the stopper of Fig. 9 resting upon the tops of the detents 35 effectively support the respective stopper in elevated position and are movable to a seating position at the annular contact line 92, indicated in Fig. l0, merely by rotation of the lugs 90 to positions intermediate the detents 35. Instead of the finger type projections 37 of Figs. 1 and 1l, vertically elongated projections or short vertical ribs 97 may be used below the lip 38 in Fig. l2. These projections 97 are stepped at 98 so that the resultant outstanding shoulder will rest upon the annular bead 32 to hold the stopper 12 in elevated position for water flow. The lower end portions may be further stepped inwardly at 99 to serve better as guide means. For stopping water dow, the stopper is forced downward, thereby compressing the upper portions of the projections inward, until the sealing lip 38 engages the annular seat 33 of the bead 32. A uniform seal is assured by bearing of the lip 38 against the under side of the overlying rolled rim 100 of the cap member 13. The projections 97, thus compressed, center the stopper 12.

As to the thin stainless steel of which the sleeve 10 is made, and of which preferably the metal cap 13 of the stopper 10 of Fig. 1 is made, this is a thin rustless steel which in practice commonly has a thickness of about .037 inch or if desired within a range of about 0.025 to 0.04 inch so that it may be readily stamped, spun and otherwise conveniently formed as required and as indicated. Thus, when a truly stainless steel is employed for the purpose of producing the sleeve 10, and likewise the cap 13, a highly desirable, very durable and thoroughly eicient structure is simply and inexpensively produced, in contrast to the production operations required in normal sink sleeves, especially for large sink drainage openings employed in connection with garbage disposal devices, wherein the materials used have thicknesses of about 0.1 inch or in specific connections 0.093 inch. From the foregoing, it

is very apparent that valuable sink outlet and stopper arrangements have been produced by this invention which provide moderately ysimple and very ecient stopper devices conveniently cooperating vwith the easily spun inwardly extending bead structure 32 supporting any of the Stoppers in open or sealed position as the case may be, the external groove of the bead providing on its lower side an upwardly directed supporting face to carry the split ring 15 from which the disposal device is suspended, such supporting face, as seen in Fig. lA, being generally flat to provide an adequate seat for he ring. Also, to facilitate installation, upper outer wall portions of the rubber suspending neck 24 are provided with spaced shallow detents above which the carrying ring 16 may be snapped and held in position while installing the bolts 20.
